SPECIFICATION forming part of Letters Patent No. 772,466, dated October 18, 1904.. Application iiled August 10, 1903. Serial No, 168,872.I (No model.)

T0 @ZZ whom it may concern: Y y

Be it known that I, JAMEs M. LooKEY, a

citizen of the United States, residing at Faulk-v To the-above'ends the invention consists ofy the novel devices and combinations of de.-l

vices hereinafter described, and defined in the claims. l

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 shows the apparatus in side elevation. Fig., 2 shows the apparatus partly in side elevation, but principally in vertical section. Fig. 3 Yis a perspective view of the detached nasal tube. Fig. 4 is a detail, partly in vertical section and partly inside elevation, showing the so-called evaporating chamber or cup and the vapor-outlet 22, said parts y being separated; and Fig. 5 is a horizontal section on the line m5 m5 of Fig. 2.

' As illustrated in the drawings, the numeral 1 indicates a rectangular housing which affords a base for the v aporizing apparatus.

proper, which vaporizingapparatus involves a cylindrical case 2, having at'one side a door 3 and having at its top a removable dome-like cover 4. The case 2 -and the door 3 are provided near their lower portions with air-inlet passages 5. the insertion of an alcohol-lamp 6 near the lower portion of the case 2, and to hold said mingling-chamber, as will presently more fully appear.

Thedoor'2 when opened permits An air-supplying tube 9 leads from a source of'air-supplying pressure into the spherical chamber 8. As shown in the drawings, the said tube 9 leads from a fan 10, located within the shell 1. This fan may be `driven in any suitable way by means not necvend a lpair of prongs terminating in perforated nose-pieces 15. The threaded end 14 of -said nasal tube is adapted to be inserted through a perforation Vin dome-like cover l and to be screwed into a threaded sleeve 16 of the commingling-chamber'8. yWhen the said nasal tube is thus applied in working position, its flange 13 presses on top of the dome 4: and securely supports the comminglingchamber in working position.

Within the case 2, above the lamp 6 and below the commingling-chamber 8, is a watercontaining cup 17, having a cover 18, into which is inserted either by screw-threaded engagement or by engagement under friction, so that the two parts will be detachably, but quite securely, held together, a smaller cup 19, which affords an evaporatingchamber secured to or cast integral with the cover 18, so that it depends into the-water e, contained within the largerrcup 17. The cover 18 is provided at its center with a funnel-like flange 2O and a screw-threaded perforation 21. The lower end of the vapor-tube 22 is adapted to be screwed into the perforation 21 and to beinserted through a closelyfitting perforation in the lower portion of the commingling chamber 8. A laterally-bent tube 23 is, as shown, rigidly secured to the cover 18 and communicates with the steam chamber or waterjacket formed around the evaporating-cup 19 within the water-cup 17. This laterally-bent tube 23 is passed outward through a perforation in the side of the case 2, and the sleevelike end of a thin metallic bulb 24 is frictionally telescoped onto the same. This bulb 24 affords a condensing-chamber for the steam, which will enter the same from the cup 17 through the tube 23, and to prevent excessive -pressure in said bulb it is provided with a vent or small perforation 25. The tube 23 assists in holding the cup 17 in Working position, as shown in the drawings; but to further hold the same and the cover 18 and evaporating-eup 19 a horizontally-extended bracket is secured to and Within case 2, as best shown in Fig. 5. The' inner end of the bracket 26 is bifurcated at 27, so that it embraces the funnel-like iange 20 of the cover 18. If desired, other devices may be used to hold the said parts 17, 18, and 19 in working positions; but the above-described means will usually be found sufficient.

The medicine or curative substance which is to be commingled with the air to form a vapor to be inhaled is placed Within the evaporating-cup 19 and is preferably in liquid form, as indicated at z in Fig. 2. The lamp 6 being then lighted, the water 2 will be boiled and more orless thereof converted into steam, which steam will rise through the tube 23 into the condensing-bulb 24 and by contact with its relatively cold Walls will be condensed and run back into the cup 17. The liquid medicine z, while it cannot be burned by the hot water and steam which surrounds the cup 19, will be heated to such an extent that a sufiicient quantity thereof will be Vaporized and will pass upward through the vapor-tube 22 into the eommingling-ehamber 8, where it will be eommingled with the air which is being driven through the air-supply tube 9 into the commingling-chamber 8 and out through the nasal tube 12. Hence the air which is delivered from the nasal tube will be medicated or commingled with a vapor of the particular medicine which is being used. In case there should be a slight condensation of the vaporiZed medicine within the eommingling-chamber 8 suflicient to leak through the joint between the vapor-tube 22 and the shell of the eommingling-cham'ber 8 such condensation wouldrun down said tube and be caught by the funnel 20, from whence it will be permitted to run back into the cup 19 when the said tube is unscrewed and removed from its seat in the cover 18.

The apparatus described is capable of modifications within the scope of my invention as set forth and claimed.

That I claim, and desire to secure by Letters Patent of the United States of America, is as follows:

1. In a vaporizer, the combination with a case and a lamp in the lower portion thereof. of a commingling-chamber in the upper portion of said ease, a water-jacketed medicine cup within said case, above said lamp and below said commingling-chamber, and having communication with said commingling-charm ber through a small tubular passage, said water-jacketed cup and said commingling-chamber being subject to the heat of said lamp, a fan having a discharge-tube leading into said commingling-chamber, and a discharge pipe or tube leading from the said comminglingchamber, substantially as described.

2. In a vaporizer, the combination with a water-jacket, medicine-cup and a commingling-chamber communicating therewith, of means for producing a iow of air through said eommingling-chamber, and a condensing'- tube leading from the water-jacket of said medicine-cup, substantially as described.

3. In a vaporizer, the combination with a case 2 4, of a commiirgling-chamber 8 in the upper portion of said case, the air-supply tube 9 passed through the side of said case and delivering into said commingli11g-chamber, the air-outlet tube 12 leading from the upper por tion of said commingling-chamber outward through the upper portion of said case, the lamp 6 in the lower portion of said case, the water-jacketed medicine-cup made up of the cup-section 17 and 19, and cover 18, said cover 18 having the flange 20, and perforation 21, the vapor-tube 22 fitting said perforation 21 and extending upward into said comminglingchamber 8, and the condensing-tube 23 extending from the water-jacket of said medieine-cup, out through said case and having at its upper end a condensing-bulb 24;, substantially as described.

In testimony whereof I have aliixed my signature in presence of two witnesses. JAMES M. LOCKEY.
